Instructions for Converting the LV/MB Joystick from ‘A’ to ‘A1’
Use along with drawings: LV2-HA & LV2-HA1
Disassembly of the “A” configuration:
1. With a 9/16” wrench, remove the handle assembly, i.e. the control knob (LV40), the joystick
handle (LV21), and 9/16” hex nut (LV11)
2. Set the handle assembly aside.
3. Slip rubber dust boot (LV27) over the retaining plate (LV22), then the entire joystick
mechanism
4. Set the dust boot aside.
5. With a 3/16” Allen wrench, remove the large button head cap screw (S048)
6. Set large button head cap screw aside
7. With a 5/32” Allen wrench, remove the two (2) small button head cap screws (P1985)
8. Set the small button head caps screws aside
9. Remove the rod end retaining plate (LV66) and the joystick handle link (LV69)
10. Set the rod end retaining plate and joystick handle link aside
11. Remove the three (3) 7/16” hex nuts (LV14) from their rods ends (P2108, and LV67 & LV68)
12. Set the 7/16” hex nuts aside.
13. Remove the spool pivot (LV67) and the spherical rod end (LV68) from the second spool.
14. Set the spool pivot and spherical rod end aside
15. Remove studded rod end (P2108) from the retaining plate (LV22)
16. Set the studded rod end aside
17. Rotate the first spool and last studded rod end (P2108) 90° CW (clockwise)
18. Remove studded rod end (P2108) from spool
a. If the spool bushing (LV30) comes loose with the studded rod end, continue to Step# 19
b. If the spool bushing (LV30) does not come loose with the studded rod end:
i. Tap it out, gently using a drive punch
ii. Reinstall in studded rod end (P2108)
iii. Continue to Step# 19
19. Set the final studded rod end and spool pivot aside
20. With a 1/8” Allen wrench, remove the two (2) button head cap screws (P1984) holding the
retaining plate (LV22) to the valve
21. Set the button head cap screws aside
22. Pull retaining plate (LV22) off of valve.
23. Set the retaining plate aside.
Joystick assembly and valve are now ready to be reconfigured for the “A1” joystick configuration.

Reassembly into the “A1” configuration:
1. Align the retaining plate (LV22) so the anchor point is below the 2nd spool
2. Install the retaining plate (LV22) flush against the valve with the anchor point facing away from
the valve
3. With a 1/8” Allen wrench, install the two (2) button head cap screws (P1984) that secure the
retaining plate (LV22) to the valve.
4. Install the first studded rod end (P2108) into the retaining plate (LV22) with the socket end
facing the first spool
a. This is the left side when viewing the valve with the joystick facing towards you
5. With a 7/16” wrench, secure the studded rod end (P2108) with one (1) 7/16” hex nut (LV14) to
the retaining plate (LV22)
6. Install the second studded rod end (P2108) and the spool bushing (LV30) in the spool directly
above the retaining plate anchor
7. Rotate the installed studded rod end (P2108) and the spool 90° CCW (counter-clockwise)
a. The threaded ends of both the studded rod ends (P2108) should be pointing in the
same direction
8. With a 7/16” wrench, secure the studded rod end (P2108) with one (1) 7/16” hex nut (LV14) to
the second spool
9. Rotate the 1st spool until it is perpendicular to the 2nd spool
a. If you are converting from “A” to “A1”, this was done during disassembly
10. Install the threaded end of the spool pivot (LV67) thru the bottom of the 1st spool
11. With a 7/16” wrench, secure the spool pivot (LV67) to the 1st spool with a 7/16” hex nut (LV14)
a. When installed the threaded end of the spool pivot and hex nut will point upward in the
same direction as the fluid work ports
12. Align the small grooves in the rod end retaining plate (LV66) with the flats in the tapped end of
the studded rod ends (P2108) already installed
13. With a 5/32” Allen wrench, secure the rod end retaining plate (LV66) to the studded rod ends
using the two (2) small button head cap screws (P1985)
a. When installed, the flat on the rod end retaining plate will face to the left, when looking
at the valve with the joystick facing you.
b. If you just disassembled the “A” configuration, the joystick handle link (LV69) will still be
attached to the rod end retaining plate (LV22)
14. Install the socket end of the spherical rod end (LV68) into the spool pivot (LV67)
15. With a 3/16” Allen wrench, secure the spherical rod end (LV68) to the rod end retaining plate
(LV66) using the large button head cap screw (S048)
16. With a 9/16” wrench, install the joystick handle link (LV69)
a. If you just disassembled the “A” configuration, skip this step and continue to Step #17
17. Slide the rubber joystick boot (LV27) over the joystick mechanism with the square end of the
boot facing the valve until the retaining plate (LV22) rests in the first groove of the rubber
joystick boot and the joystick handle link (LV69) is thru the round hole of the rubber dust boot.
18. Install the handle assembly (LV11, LV21 & LV40) into the joystick handle link (LV69)
19. Secure the handle assembly (LV11, LV21 & LV40) by tightening the 9/16” hex nut (LV11)
The joystick is now converted to the “A1” configuration.
